Application nledune is,

f To all whom may concern:

' work ha Be it known that ll, Annie F. llatiitrorr, a citizen ot the United States, residing at Streator, in the county of La Salle and State of illinois, havel invented a 'certain new and useful improvement in Bricks,l of which the 'following is a specication.

This invention relates to building inaterial, more particularly to artiticial brick. used in buildingl walls. "llhe object or the invention is to provide a brick ci such a construction that a series oil2 them can be fitted together, preferably, but not necessarily, without the use ot inotar in such a manner that all points between adjacent brick are practically self-sealed and Vbetter still, of such a construction that when one row of brick in a building has been placed by a skilled artisan, the courses of brick above may be put in place by a workman of just ordinary ability, the resulting wall ben ing, however, it the work was started right, practically as satisfactory as though all the been done by the highest class workman. y

llhe invention consists in a brick capable of `.attainingthe foregoing objects, which i can be easily and cheaply made, which is saisfactory in use and is not readily liable to get out of order. 'More particularly, the invention consists in many features' and details of construction hereafter more fully set forth in the speciication and claims.`

Referring to the drawings, in which like numerals designate the saine parts through out the several views,

Figure lis a perspective view of one cornplete brick embodying this invention in its preferred form.

Figure 2 is a side view of tion of brick ot Figure 1..

Figure 3 is 'a horizontal sectional view taken on the line 3 3. of Figure 2.

Figure 4 is a transverse sectionalI view taken on the line .1l- 4, Figure 2.

Figures 5 and 6 are perspective views of corner bricks embodyin this invention to be placed at the corner o the building, .being constructed in the light or this invention. 1

1 The invention is lpplicable' to brick of any configuration. Verel the drawings show -the invention applied to a' conventional form of brick of about 2 idx8 inches.

any material, butordinarily will be made or cement Atorrned in a suitable inold 'to produce the structures or" Figure 1 ures 5 or 6.

F or the purposes or the side wall the building the brick take the -torni oitr Figu ure 1 in which there is a central body poru tion 10' substantially the torni as an ordinary brick of commerce. Cast integral with and on opposite sides ot this body are rectangular plates 12 and 14 ot substantially,

usually three eighths of an inch lessl length and height than the brick body 16, but-ot only such `thickness as may be dictated by requirements of strength to enable these members 12 and 1li to withstand the usage which is required of them, both in building construction and in 'shipping'.

Each plate 12 and. 141 is diagonally ori-set with reference to the adjacent. side ot the brick so as to provide at one end adistance 16 of say three-quarters of an inch on an 8 inch brick between the end 18 oi the plate and the end 20 or the brick and to correspondingly provide a downward step or space 22 ot-say three-quarters or an inch between the upper edge 2st of the lplate and the upper surface 26 of the brick, the re'- sult bein-g that the plate forms 'a flange correspondingly overhanging the lower surface 28 or the brick by spaceBO of about three-eighths of an inch and it forms a flange overhanging the end. 32 of the brick by a corresponding distance or space 3i, of about three-eighths of an inch.

rllhe width of the brick 10 may, in the proc-A ess 'of manufacture, be suiiciently accurately vdiin'ensioned so thatv when the brick are interlitted as shown in igure 4C, the surfaces 26 and 28 bearing on each otherbetween the downwardly turned ange portions of the side plates12 and 14 of upper brick, all overlap and accurately tit upon the upper portion of the lower brick with sulicient-tiglitness so that if skilled workmenset` the first curse -of brickat thebottom of a wall plumb, ad-

ditional brick may be tted in successive courses upon it by a more or less unskilled worknian with 'comparative assurance that the accurate lit of the successive. courses of the brickone on the other will forcethe wall to. rise in an exactly plumb vertical plane,

and that this will occur practically regardless of the ability of the workman.- The cor-y ner bricks of Figures 5 and 6 do not diiler in principle from the plane wall brick of y Figure l. In fact, they diHer from Figure 1 only that they with their side plates turn a corner between their intermediate ends.

In constructing a wall in connection with 5 this invention, itis the best practice to use a suitable cement in the interfitting spaces between the successive brick, both side ways and vertically, such cement being of such character that it does not occupy substantial space, thereby doing away with distortion in the form of the wall, due to the presence of 4 mortar in irregular texture and quantity.

Attention is called to the fact that while the overlapping flanges produced by the plates 12 and 14 cover practically all joints between adjacent brick. L

The proportions ofthe plates are such that regularl vertical and horizontal mortarless spaces, say three eighths of'an inch in width, are left between the adjacent plates, the same being known in the brick trade as arake joint and very much sought after where expense will permit. The use of the brick of this invention produces this rake joint effect nary brick laying, whereas without this invention, after the ordinary brick is laid in mortar, the mortar must be raked or gouged out to a depth of three-eighths of an inch, thereby wasting mortar and labor; or, inthe original `brick laying, some three-eighths of an inch sticks are placed between the edges of the brick, and themafter the bricks are laid the sticks must beremoved, leaving a mortarless joint, looking as though the mortar had been raked out, thereby causing great waste and labor in preparing sticks for this pur ose, inserting them between each brick an laterl removing them. The use of Athis invention does away with all the waste mortar and mortar stains which necessarily occur in the above prior constructions.

at practicallyi no additional cost over ordi- Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A wall made up of a plurality of blocks arranged in superimposed relation and each having a projecting side facing formation, one end and one side edge portlon of which extends beyond the adjacent end and side of the body thereof and its other end and side portions bein disposed inwardly with respect to the re ated end and sideof the body a relatively greater distance than its first mentioned side and end portions extend beyond the body portion, said blocks being so disposed that all edgesof the facing formations thereof are relatively spaced apart and the joints between the body portions of the blocks are covered thereby.

2. A wall made up of a plurality of blocks arranged in superimposed relation and each having a projecting side facing formation, one end and one side edge portion of which extends beyond the adjacent end and side of the body thereof an-d its other end and side portions being disposed inwardlyv with respectto the related end and side of the body a relatively greater distance than its first mentioned side and end portions extend beyond the body portion, and mortar between the body portions of sai-d blocks for binding the sametogether, said blocks being so disposed that all edges of the Ifacing formations-thereof are relatively spaced apart and the mortar-between the blocks is covered and protected by said side facing formations.

In witness whereof, I have hereunto `Subscribed my name:E in the presence of two witnesses.
